Can Gas Jet process challenge electrospinning in producing polymeric nanofibers?

E-mail Print PDF

A team of scientists from the University of Akron, Ohio (USA) has reported a novel and yet an effective method to produce polymeric fibers. The fibers could range from a few tens of nanometers to a few micrometers in various morphological forms (smooth or wrinkled) at 10-20 times higher rate than the published rate of a single electrospinning jet. The authors of the report termed the process as Gas Jet Nanofibers (GJF).

How various processing variables influence polymeric fiber (such as polyethylene oxide and polyvinyl pyrrolidone ) diameter and its morphology have been described. According to the report, the GJF process benefits from the balance of various forces originating from viscous, surface tension, and aerodynamic sources.

Professor Sadhan Jana, lead researcher says, “The process gives us flexibility and opportunities to aid industry in quest for large quantities of nanofibers. In addition, the process already aided us in the discovery of unique nanofiber morphologies”.
